RMAN-00571: ===========================================================
RMAN-03002: failure of recover command at xx/xx/2023 11:17:16
ORA-19698: +DG/db_name/redo_file_name is from different database: id=722521960, db_name=db_name</pre>

   <div class="section">
    <h4 class="sectiontitle">可能原因</h4>
    <p>Oracle异机恢复时，如果目标位置下存在其他数据库的同名redo文件，Oracle将尝试直接使用此redo日志进行恢复，由于此redo日志文件是其他数据库的，故报此错误。</p>
   </div>
   <div class="section">
    <h4 class="sectiontitle">处理步骤</h4>
    <ol>
     <li><span>修改冲突的数据库的redo文件路径，并从文件系统中将redo文件移动到其他位置。</span></li>
     <li><span>重新执行恢复任务。</span></li>
